Coronary heart disease has traditionally been seen as a male problem, but in reality it is the main killer of women.
This is the stark message health campaigners are trying to get across to the women of Merseyside, where heart disease in women is 30% above the national average.
One of the biggest studies of women and heart disease has also discovered that women who have a history of heart disease are less likely to be taking the recommended medicines to stay well.
Dr Diana Forrest from the Heart of Mersey campaign and Dr Debbie Lawlor from the British Women's Heart Health Study join Jenni to discuss why women at risk seem to be getting different treatment to men, and women's attitudes to heart trouble.
